Randomized Controlled Trial
NRD.E1, an innovative non-opioid therapy for painful diabetic peripheral neuropathy - a randomised proof of concept study.
Painful diabetic peripheral neuropathy (PDPN) affects up to 26% of patients with diabetes mellitus, with major impacts on their general health and well-being. Most available drugs fail to deliver acceptable pain reduction in the majority of patients and are often poorly tolerated. NRD.E1 is a novel product that has shown anti-nociceptive preclinical effects and good tolerability in healthy volunteer studies. ⋯ NRD.E1 is a novel non-opioid therapeutic which is being developed for the treatment of PDPN. In this randomized, controlled, dose-finding, Proof of Concept study, NRD.E1 induced a clinically relevant pain reduction and it was well tolerated. Available data suggest that NRD.E1 has at least similar efficacy and better tolerability than the currently available therapies, potentially offering a promising new therapeutic option to patients with PDPN and possibly other neuropathic pain indications.

Identifying predictors of poor postoperative outcomes is crucial for planning personalized pain treatments. The aim of this study was to examine pain outcomes using cluster analysis in N = 2678 patients from the PAIN-OUT registry at first postoperative day. ⋯ Improvement of postoperative pain requires assessment methods that go beyond pain intensity scores. We perform a cluster analysis among PAIN-OUT patients that revealed a cluster of vulnerable postoperative patients, using a novel composite measure of postoperative outcomes: the factor scores of the International Pain Outcomes Questionnaire. By changing the focus from pain intensity to multidimensional pain outcomes, male gender and number of comorbidities appeared as new risk factors for worse postoperative outcomes. The study also identified procedures that require urgent quality improvements.

Chronic pain is a major healthcare issue posing a large burden on individuals and society. Converging lines of evidence indicate that chronic pain is associated with substantial changes of brain structure and function. However, it remains unclear which neuronal measures relate to changes of clinical parameters over time and could thus monitor chronic pain and treatment responses. ⋯ Thus, changes in chronic pain might be reflected by global network changes in the theta band. These longitudinal insights further the understanding of the brain mechanisms of chronic pain. Beyond, they might help to identify biomarkers for the monitoring of chronic pain.

Current literature in pediatric pain evaluates the Fear Avoidance model (FAM) pathways at the trait (or macrotemporal) level, but it is unknown if these pathways also occur at the state (or microtemporal) level. Identifying microtemporal processes can improve our understanding of how the relationships within the Fear Avoidance constructs vary when specific Fear Avoidance variables wax and wane. We hypothesized that changes in FAM constructs would be associated with changes in the next variable in the sequence on a microtemporal level, including: (1) higher pain when there is more pain-related fear, (2) higher pain-related fear when there is more avoidance, and (3) higher avoidance when there is more reported disability. ⋯ The current study suggests that the ways in which the FAM is related to various aspects of pain functioning differs on a state-level, which adds new clinical and research opportunities.
